Bio:The man known as Darklon was from a long line of mercenaries and profiteers, and he is as greedy and amoral as any of them ever were. His family's ancestral home is an imposing castle in the tiny nation of Darklonia. Darklon is actually a distantly related cousin of Destro. Darklon became involved with Cobra shortly after Destro took control of the organization. Darklon was selling surplus Cobra and G.I. Joe vehicles, and Destro wanted test subjects for Dr. Mindbender's Pythonizing process, which rendered vehicles invisible to radar. Darklon sold Cobra a number of vehicles, testing them by sneaking over Darklonia's border with Wolkekuckuckland. Eventually, Darklon joined with Destro's Cobra and took over the leadership of the Iron Grenadiers when Destro and the Baroness took time off away from Cobra. When Cobra began occupying parts of Sierra Gordo, Darklon led an attack on nearby Punta Del Mucosa. Later, he led a small army of Grenadiers against the country's native Tucaros, who were allied with a team of Joes and the October Guard. After Destro severed his ties with Cobra, Darklon returned to his business interests in Darklonia. Years later, when Cobra took over neighboring Borovia, Cobra Commander brainwashed Destro into service and commandeered his castle in nearby Trans-Carpathia. When the Commander suggested Darklon was a threat to them, Destro casually launched a missile at Castle Darklon. The resulting explosion killed Darklon and destroyed much of his castle.
